English2.3.4 Flexible tracing or locking See figure 5The tracer point is the axis protruding from the left side ofthe machine head, seen from the front. This tracer pointhas two operating modes, depending on the work to becarried out:1 Flexible tracer point: With the flexible tracerpoint, key cutting is performed with verticaladvance (Z-axis). Duplication by points.2 Tracer point locked: With the tracer point locked,key cutting is performed with horizontal advance(X- and Y-axes).To switch from “tracer point locked” to “flexible tracerpoint”, simply loosen the corresponding knob. To switchfrom “flexible tracer point” to “tracer point locked”, pushthe tracer point upwards manually and when it reaches itslimit, lock it in place with the corresponding knob.2.3.5 Vertical tracer point adjustment See Figure 6Place the two keys in the clamps (the original key in theleft-hand clamp and the key to be cut in the right-handclamp).Make the adjustment as follows:• Place the tracer point in “tracer point locked” operatingmode.• Lower the head and rest the tools on a flat part of thekey, without pressing down.• When the tools make contact with the keys, there arethree possibilities1 The milling cutter and the tracer point make contactwith their respective keys at the same time.This means the machine is correctly adjusted.2 The tracer point makes contact with the key, butthe milling cutter does not.If this situation occurs, the vertical position of thetracer point needs to be adjusted, raising the tracerpoint. This is done as follows:- Place the tracer point in “flexible tracer point”operating mode.- Lower the head and rest the tools on a flat partof the key, without pressing down.- Unlock the tracer point depth adjustment wheeland turn it anti-clockwise until the milling cutterand the tracer point make contact with theirrespective keys at the same time.- In this position, lock the adjustment wheel usingits locking nut.3 The milling cutter makes contact with the key,but the tracer point does not.If this situation occurs, the vertical position ofthe tracer point needs to be adjusted, loweringthe tracer point. This is done as follows:- Place the tracer point in “flexible tracer point”operating mode.- Lower the head and rest the tools on a flat partof the key, without pressing down.- Unlock the tracer point depth adjustment wheeland turn it clockwise until the milling cutter andthe tracer point make contact with their respectivekeys at the same time.- In this position, lock the adjustment wheel usingits locking nut.2.3.6 Changing the milling cutter and tracer pointSee figure 7• To release the milling cutter, simply loosen thetwo setscrews on the milling cutter holder shaftand remove it. Insert the new milling cutter,making sure it reaches its limit.• To release the tracer point, simply loosen the setscrewon the tracer point holder shaft and removeit. Insert the new tracer point, making sure itreaches its limit.2.3.7 Motor operation See figure 8• On the right side of the machine there is a twowayswitch (0/I) for activating the milling cutterrotation speed:- 0 > Milling cutter off- I > Milling cutter rotating10
